Described cylindrical shell, top cover labyrinth and taper screen cloth three's central lines, and contact-making surface all seals and joins between the three.
The described diameter of going up the diameter of disk less than lower disc; Two disc thickness are 2～40mm, and diameter is 20～1000mm.
Described threaded rod length is 10～3000mm, and the spacing of upper and lower two disks is adjustable up and down along threaded rod.
Described fluid input tube and wake flow efferent duct are uniformly distributed in taper screen cloth inboard along the cylindrical shell lower surface, the distribution number is 1～16; Described smart stream efferent duct is uniformly distributed in the taper screen cloth outside along the cylindrical shell lower surface, the distribution number is 1～16.
Characteristics of the present utility model are:
1, the employing fluid input mode opposite with gravity, make powder granule realize the ascending arrangement of particle diameter along gravity direction in screen cloth inside, the particle of having avoided each grade when the conventional screen subset sieves is effectively all concentrated the problem of the face sieve that results in blockage to screen cloth, it is all-round by screen cloth effectively to have guaranteed to be lower than a certain other particle of level, has improved the efficient of screening.
Need not to set up dispersed with stirring equipment when 2, this instrument is worked, the power that relies on continuous fluid input ceaselessly to wash away the stirred fluid generation has been realized intergranular dispersion.
3, to have changed traditional wet classification equipment be to realize whole screening operation mode by the clearance-type feed to this instrument, can regulate liquid according to the height of fluid solid content and send into speed, input quantity and input time, the disposable classification fluid that will need to handle carries out graded operation continuously.
The utility model adopts the fluid input mode opposite with gravity, make powder granule realize the ascending arrangement of particle diameter along gravity direction in screen cloth inside, the particle of having avoided each grade when the conventional screen subset sieves is effectively all concentrated the problem of the face sieve that results in blockage to screen cloth, it is all-round by screen cloth effectively to have guaranteed to be lower than a certain other particle of level, has improved the efficient of screening.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, this stirs continous way certainly and filters the screening grading instrument, comprise cylindrical shell 2, and the grading instrument cavity that constitutes of the top cover labyrinth 1 that places cylindrical shell 2 end faces, wherein: the grading instrument inner chamber is provided with the threaded rod 6 through cavity, and the last disk 3 and the lower disc 4 that are connected in these threaded rod 6 upper and lower sides, along the continuous conical screen net 5 that is connected to of lower disc outer circumference surface on two; On the bottom face of cylindrical shell 2, be provided with fluid input tube 7, wake flow efferent duct 8 and smart stream efferent duct 9.Cylindrical shell 2, top cover labyrinth 1 and taper screen cloth 5 threes' central lines, and contact-making surface all seals and joins between the three.The diameter of last disk 3 is less than the diameter of lower disc 4; Two disc thickness are 2～40mm, and diameter is 20～1000mm (seeing Fig. 3, shown in Figure 4).
Threaded rod 6 length of this grading instrument are 10～3000mm, and the spacing of upper and lower two disks can be according to the height of shell along threaded rod distance between the swivel disk about in the of 6.The appearance that taper screen cloth 5 wrapped up and be fixed on two disks requires wire side smooth.
As shown in Figure 2, fluid input tube 7 and wake flow efferent duct 8 are uniformly distributed in taper screen cloth inboard along cylindrical shell 2 lower surfaces, and the distribution number is 1～16; Described smart stream efferent duct 9 is uniformly distributed in taper screen cloth 5 outsides along cylindrical shell 2 lower surfaces, and the distribution number is 1～16.
The utility model cylindrical shell 2 is connected as a single entity with fluid input tube 7, smart stream efferent duct 9 and wake flow efferent duct 8; Cylindrical shell 2 is a cylindrical tube, and fluid input tube 7, smart stream efferent duct 9 and wake flow efferent duct 8 weld with round steel pipe with cylindrical shell 2 junctions.
During the equipment assembling, earlier taper screen cloth 5 is put into cylindrical shell 2, cover top cover labyrinth 1 lid then; Require taper screen cloth 5, casing cylinder 2 and top cover labyrinth 1 three's center line to overlap, and encapsulation process is all wanted in the place that is in contact with one another between the three.
During the instrument operation, close wake flow efferent duct 8 earlier, the operation instrument, fluid enters instrument internal through fluid input tube 7, removes at taper screen cloth 5 and realizes classification, and the granular powder littler than taper screen cloth 5 apertures flows out by smart stream efferent duct 9, the granular powder bigger than taper screen cloth 5 apertures will be stayed in the taper screen cloth 5, screening is opened wake flow efferent duct 8, the big granular powder in delivery ratio taper screen cloth 5 apertures after finishing.
Design principle of the present utility model is: adopt the fluid input mode opposite with gravity direction that powder is carried out sieve classification.Enter the particle of taper screen cloth 5 through fluid input tube 7, be subjected to three active forces altogether, the glutinous flow resistance of the buoyancy that promptly makes progress, fluid and downward gravity; Input rate one timing when fluid, three suffered active force sums of a certain size particles are zero in the fluid, particle will be in static relatively suspended state, to move upward less than this size particles, by the taper screen cloth, from essence stream efferent duct, flow out, will move downward greater than this size particles, flow out from the tail effuser, this has just realized the purpose of gradation.The design has three big characteristics, and promptly screening efficiency height, realization are from stirring and the screening process serialization.
Above content is to further describing that the utility model is done in conjunction with concrete preferred implementation; can not assert that embodiment of the present utility model only limits to this; for the utility model person of an ordinary skill in the technical field; all any simple modification and equivalent structure transformation or modifications of doing according to the utility model spirit essence all belong to the definite protection domain of claims that the utility model is submitted to.
